Abstract

We report on properties of hadronic events from e+e- annihilation observed by the ALEPH detector at the large Electron Positron Collider at CERN. The center-of-mass energy was s=91.0-91.3 GeV. Measured distributions of the global event-shape variables sphericity, aplanarity, thrust and minor value, and of the inclusive variables xp, p⊥in, p⊥out and y are presented. We measure a mean charged multiplicity in hadronic events of 〈Nch〉=21.3±0.1 (statistical)±0.6 (systematic). The data are in good agreement with QCD-based models which use the leading-logarithm approximation, and are less well described by a model using O(αs2) QCD. © 1990.
